I had the same look to my o/d oil, and thanks to the folks at Robertsons I found out that I actually caused it when I changed it the previous time. So here is what they told me, when you change the oil there is a little orange washer on both plugs, this is a crush washer and should be only tightened one time then replaced- they are cheap, but it made sense to me and no probs now... I have a Yamaha 90 ob.
